| Abstract | A surveillance system is quite useful to estimate actual traffic-state dynamically at any time and place. It would provide useful information about current traffic conditions in the networks to the drivers. The surveillance system would store the traffic data for future planning. Traffic simulation programs play an important role in surveillance systems. Simulation programs help to predict future traffic situations on the network systems and aid in determining congestion alleviation measures through experimentation. The principal goal of this study is to develop a macroscopic traffic flow simulation program for an expressway network in Bangkok. This study presents a simulation program which can be applicable for the surveillance system. In this study, a macroscopic model is used for the development of simulation program because there are more than ten thousands vehicles in an expressway network in Bangkok. Traffic data collection was done using video cameras on second stage expressway in ding daeng to chaeng wattana section in Bangkok on 24th October 1997. Modification and extension of the existing traffic simulation program is done to describe the traffic phenomena specific to Bangkok. The effect of on-ramp flow was considered and the lane-changing concept was also discussed briefly. Sensitivity of model parameters is investigated and systematic procedure for calibrating is established. Comparison of the simulation outputs is done with measured values and with FRESIM simulated values for the calibration and validation of model parameters. |
